Elite colleges and universities enroll — and graduate — some of the wealthiest people on earth.

Each year, research firm Wealth-X identifies the colleges and universities with the highest number of "ultra high net worth" (UHNW) alumni, defined as those with a net worth of greater than $30 million.

Wealth-X first collects a sample of ultra-wealthy individuals known to have a diploma, including both undergraduate and graduate degrees, from colleges and universities around the world, and tallies their total wealth as a group. Researchers then use this sample and Wealth-X's database to estimate how many super-rich alumni each school has graduated in total.

Here are the 20 universities around the world with the most ultra-wealthy alumni:

Harvard stands out as having the highest number of ultra-wealthy alumni by far. According to Wealth-X's projections, the Ivy League school has an estimated 13,650 alumni who are worth more than $30 million, more than double the number of super-rich alums from Stanford and the University of Pennsylvania, which landed in second and third place on Wealth-X's rankings, respectively.

All but three of the 20 schools are in the U.S.. Cambridge, Oxford and INSEAD were the only institutions outside of the U.S. to produce enough super-rich alumni to make the list.

Even though Harvard tops the list of the most super-rich alumni, the University of Chicago stands out as having the highest percentage of "self made" alumni, with net worths above $30 million, as opposed to those who have reached this status through inheritance. Wealth- estimates that 84% of University of Chicago alumni who are worth more than $30 million made their fortunes on their own.
